Resilient Streaming Anywhere: How KeySIM Supports Our Bonded Connectivity Workflow

At Bright Spark Studios, reliable connectivity isn’t a bonus — it’s essential.  Whether we’re livestreaming from a council chamber, conference centre, or a remote rural venue, our bonded internet setup is designed to deliver stable streams, even when conventional connections fall short.

One of the key components of this resilience is our use of multi-network SIMs from KeySIM.

Why Multi-Network SIMs Matter

When streaming live, relying on a single network is risky.  Coverage varies by location, and even robust 4G or 5G signals can fluctuate throughout an event. That’s why we use bonded connectivity — combining multiple internet sources to create a single, more stable connection.

KeySIM provides non-steered SIM cards that connect to all UK networks simultaneously, ensuring our Peplink routers and LiveU/Haivision encoders can always pull from the strongest available signal.

Real-Time Management Through the KeySIM Portal

Beyond connectivity, KeySIM also gives us operational visibility and control. Through their intuitive online portal, we can:

• Monitor which SIMs are currently active and where they’re being used
• Activate or deactivate SIMs as needed for specific jobs
• Access detailed insights into data usage across all devices

This makes it easy to scale our connectivity depending on the project, manage costs effectively, and ensure we’re always ready with the right capacity.

How It Works in Practice

Our typical setup might include:

• Peplink routers bonded with multiple 4G/5G SIMs (via KeySIM)
• Starlink satellite internet as a fallback in low-coverage areas
• LiveU or Haivision encoders for consistent stream encoding

This gives us a resilient pipeline for livestreams, capable of delivering reliable performance even when Wi-Fi isn’t an option and wired connections are unavailable or uncertain.

We’ve used this setup successfully for:

• Conferences
• Public sector briefings
• Livestreams in rural locations without infrastructure
• Mobile productions in temporary locations

The Result: Confidence in Every Stream

Thanks to partners like KeySIM, we can bring our own internet to the job — flexible, secure, and robust enough to handle the demands of live video production.
